The battery's life may be short due to abnormal
energy consumption during stops.
To check the residual consumption of the system,
use a multimeter with miliammeter function.
Prepare the multimeter with alligator clips instead
of conventional tips and select the full scale of 40
mA for direct current (DC).
With the battery connected as usual to the system,
connect the alligator clips to a battery pole and to
the corresponding wiring harness terminal.
With the ignition switch to Off and the electric loads
inhibited, remove the fixing screw and disconnect
the terminal from the battery pole, creating thus the
conditions of a miliammeter in series with the sys-
tem load.
For the versions with immobilizer, the load will be
pulsed with the deterrent flashing frequency. The
normal values are comprised between 2 mA with
the LED off and 15 mA with the LED on.
If significantly higher consumption is detected, it is
necessary to progressively disconnect the con-
sumers with direct power supply from the battery,
until identifying the component, the portion of the
wiring harness or any water infiltrations in the con-
nectors that may cause the abnormal consump-
tion.
In any case, it is important to check that, while
closing the saddle, the light of the compartment
underneath goes off before the saddle arrives in
contact with the lock.
